IVMPOVEMENT IN FLUID-METERS.

The Scheulejefered to in these Letters Patent and making pari:` of the same. y

Figure 3 is a diagram illustrating the-relative positions of the stationary channels and of' the movable buckets of the wheel.-

` Similar letters indicate corresponding parts.

This invention relates to a fluid-meter provided with a bucket-wheel mounted on a vertical spindle, the fluid heilig conducted to the-buckets of the. wheel through a series of contracted openings in a stationary disk, in combination-with a registering mechanism, to which the motion of' the bucket-wheel is transmitted by au' endless screw Vmounted on a prolongation of the ve'rtical spindle in such a manner that, bythe contracted openings in the stationary disk, a very small quantity ot' liquid passing through the meter is capable of imparting motion to the bucket-wheel, and a fluid-meter is obtained which is exceedingly simple in its 'cou-` struction, and capable-ot' indicating correctly all the fluid passiug through it.

The prolongation of the spindle ot' the bucket-wheel passes `through astuling-box containing alternating disks of India rubber and of metal,`so that said prolongation is packed tight-with the least possible friction. i

In the drawing- The letter A desiguatesa bucket-wheel, which is mounted on a vertical spindle, B, and surrounded by a jacket, C, fitting closely'to the circumference ofthe wheel.

Over the vwheel situated a disk, D, which is firmly secured bythe inner circumference of the jacket G, and

, which is perforated with a series ofopenings or channels, a, running in oblique directions, as shown in iig. 3, so that Vthe liquid passing down through the same will strike thebuckets of the wheel A at right angles or nearly so.

The channels a are bored out round or they are contracted in such a manner that, in case a limited quantity of liquid passes through the meter, the liquid passing down through cach ofthe channels is pre- `vented from spreading, and thus enabled to 'exert a certain impact 0n the buckets, and that the wheel A is caused to revolve by a very smallqnautity of' liquid acting on it.'

From the upper end of the yspindle Brisesan ex`z tension, E, made of thin steel wire, so as to produce.

the least possible friction in the stung-box F, and the friction is reduced to a minimum by the packing which I employ in said stulug-bo.\:. P

This packing consists ot' twodisks, b, OfIndia rubber, which alternate with disks c, of metal, as shown in tig. l of the drawing. I

On the upper end ot' the extension-E is mounted a worin-screw, (l, which transmits the motion ot' the bncket-wheel A to the registering mechanism F. n

The bottom end ofthe spindle Bruns on a pointed The liquid to be measured is admitted through a pipe, G, and it discharges through a pipe, H,V(see By these means aliquid-metcr is' obtained capable vof' recording the correct quant-ity of any liquid flowing through it, independent ot' the head or velocity with which the liquid passes through the same, the meter being so constructed that it is capable of measuring a very small quantity of liquid as accurately as a large quantity.

What Iclaim as new, and desire to secure by Let .tersPatent, is

The arrangement et' a stationary disk, D, perlbratcd with oblique contracted channels c, and fitting closely into the jacket C, over the bucket-wheel A, mounted ou a vertical spindle, B, the extension of which car# ries a worm-screw to transmit the *motion of the bucket-wheel A to the registering apparatus, all as herein shown'and described.

This specification signed by me this 7 th day of' October, 1870.
